    摘要: Hyperbranched dendron (HD) polymers are synthesized using low molecular weight polyethyleneimine (BPEI-L) as a core and used for gene delivery. The obtained polymers display low toxicity and efficient gene delivery at low nitrogen-to-phosphate (N/P) ratios. Using successive attachment of ethyleneimine moieties to a PEI core, the polymer has a lower relative ratio of linear-to-branched structures than in the core PEI. The more extensive branching enables the polymer to condense plasmid DNA into nanostructure complexes with a size of less than or equal to about 100 nm. The complexes are stable and efficient in transfecting cells in the presence of serum. Bioluminescent imaging of in vivo gene expression using a luciferase reporter gene performed in live mice showed gene expression in the liver and in submandibular lymph nodes.

    摘要: The invention provides compounds and methods of their use in the detection of apoptosis and necrosis both in vitro and in vivo. Also provided are compounds and methods of their use in selective delivery of agents to cells undergoing apoptosis or necrosis. The compounds and methods are based on conjugates formed with a dehydrogenase such as lactate dehydrogenase, alcohol dehydrogenase, aldehyde dehydrogenase, and malate dehydrogenase. The compounds and methods are useful in the diagnosis and treatment of conditions characterized by apoptosis, including cancer, cardiac disease, neurologic disease including stroke, and autoimmunity. The compounds and methods offer distinct advantages over corresponding compounds and methods based on Annexin V. Also provided are methods for screening for compounds that modulate, i.e., inhibit or promote, apoptosis.

    摘要: The present invention relates to synthetic methods for grafting hydrophilic chains onto polymers, particularly hydrophobic polymers such as poly(vinyl chloride) (PVC), poly(vinylidene fluoride) (PVDF), and chlorinated polypropylene (cPP). Resulting polymers include comb polymers which can have a microphase-separated structure of hydrophilic domains provided by the hydrophilic chains. Articles prepared from these comb polymers, particularly derived from PVDF, include membranes for water filtration in which the hydrophilic domains provide a pathway for water transport. PVC can be plasticized by grafting the PVC with hydrophilic chains. In addition, such articles, particularly articles having biomedical applications, can display anti-thrombogenic properties.
